a power supply mode:

forbidding driving, and detecting the SOC value of the power battery;

when the low value is less than or equal to SOC and less than the median value, the fuel cell module independently supplies power to the external three phases, the switch K1 is disconnected, the switch K2 is disconnected, the switch K3 is disconnected, the switch K4 is closed, the fuel cell module independently generates power, and the external three phases are supplied with power through the DC/DC booster, the DC/AC inverter and the three-phase distribution box;
